Application. filed September 16, 1926. Serial No.'135,750.

This invention relates to yarn carriers, and

. is especially intended 'tor use in connection with tutt weaving as it is practiced in the manufacture of Amninster rugs or carpets although applicable to yarn-carriers for other kinds of work.

IcIereto'i'ore in the pac aging of yarnl 'for use in Axminster tube frames and the like, it has been customary to wind the dilierent colors ot yarn, arranged in a predetermined order, on the spool or beam to produce the vdesired pattern in the fabric being woven. The individual strands or yarn elements are kept from overlapping or crossing one another until they are threaded into the tutt tubes'of' the tube-traine by means of a comb or toothed guide between whose teeth the yarn elements pass as they are being wound l on the spool. After the winding o'f the yarn on the spool a clamp `s applied to the separated yarn elements so as to hold them in regular spaced order, and such clamp is atached to the spool by means of connecting' members at its opposite ends which are engaged by the spool-journals, as shown in the United States Patent te Lea No. 1,158,870 dated Sept. 14, 1915.v

In practice, however, the endwise shifting of the clamps along the vspools often leads to the clamp being disconnected from the spool-journal, thus causing confusion and trouble.

' rIhe present invention .is intended to obviate such troubleand does so by providing the spools with n'ieans outs le ot the o'urnals ot the spool which all'ord a positiveanchorage tor the clamp-connecting elements thatjare not subjectto release by endwiscV shifting of the clamp in relationto Atheyarn-spool or beam. Y I

In the accompanying' drawings I have illustrat'cd a simple and convenient construction embodying the present improvement by which the difficulties heretofore experienced are overcome. v v

In the drawings:y

Figure 1 is a plan `View of a fully wound tutt-yarn spool with its yarn-holding` and spacing. clamp connected therewith to maintain proper order and separation of the individual yarn elements before they are drawn in to the tutt-tubes of a tubetrame.

Figure 2 is a vertical longitudinal section of the construction shown in Figure 1.

Figure 3 is an end elevation of the same4 Figure 4 is an end elevation showing `a vmodified constructionof spool head.

Figure 5 is a longitudinal section of the end portion of the spool shown in Figure 4.

Inl the practice ofthis invention, -according tothe form shown in Figures 1 to 3. of the drawings, I .employ a longitudinal cylin drical spool 11, having end heads 2, of pressed metal comprising disks 12, formed with peripheral lianges 1-1 and with a" center oiset hub 15, whicii engages the barrel 1l to which the two heads are firmly secured' in any suitable manner. Jonrnals'l?) are inserted aXlyally in the endsof the barrel to, Vrotatably support 'the spool inthe tube trame to allow unwind'ing ot the yarn. f y

At some convenient point'between the journal and the peripheryof each head,` I provide anchoring means so constructed and arranged as to ailord an anchorage'for the clamp-attaching or connecting elements so as'to form a positive interlocking engagement with Athe clampseonnecting elements that is not affected by longitudinal shifting of the clamp on the spool'. these anchoring members are in the form of hoek-like tongues or spurs struck out 'from the lat disk portion of the spool'heads 2, and pointing inwardly so as to reeeiveand retain the connecting members which7 in this ease7 comprise helical springelements 8 provided with eyes .or loops 9, at their free ends to permit themto be slipped over the inwardly turned Vspurs or hools 16, when the spring is distcnded.

` The clamping member itself is similar-'to In the form shown in Figures 1 to 3 that shown in the Iiea patent' aforesaid` and comprises a comb member'i and 'a troughlike cover 6 which closes the slots in the comb' when slipped'over the outer ends of the teeth, said cover being kept inplace by means ofthe hook members 7 overlapping the opposite ends of the cover element of the clamp. The projecting ends of the comb member are provided with pcr'forations into which the elastic attaching yelement is'hooked.

It will be observed that as the springs 8 are under tension7 such tension tends to y draw the eyes or loops 9 of the spring` toward the 'base of the hook member 16 and away 'from the points thereof. fFurthermore, Aas 'these hochr members are disposed to so engage thel free ends of the distensible connecting elements, not onl is the disengagement ot such springs from t eir anchorages along the spool prevented, but asthese anchoring elementsVv 16 serve to resist longitudinal movement, as

well as outward movement of the clamp, the accidental shifting of the clamp along the spool isV reduced to a minimum.

The saine principleis also applicable to the spools having wooden heads, and in Figures 4 and 5 I have shown a Convenient means for applying the improvement to a spool with wooden heads. In this case the barrel 22 carries Wooden heads or disks 19 to whose outer faces is secured a pressed steelv ring or dish 18, having anchoring ling-ers or hoolis 17, struck out from the body thereof. This metal disklS mayl be secured directly against 'the face of the wooden head by means of attaching screws 20, or in any convenient manner.

The above described construction permits the yarn-Wound spools, with their yarn-holding and spacing clamps, to be transferred from one part of the mill to another for storage or. for use without endangering the sep- `aration of the yarn-clamp from the spool,

Vandthusreinm/es a great source of trouble and loss heretoforeexperienced.

`What I elaimis:

' l. A yarn. carrier embracing inV combination a longitudinal'spool barrel andits yarnretaining end-heads, axially disposed journals for rotatably supportingl the spool in suitable bearings, and means located intermediate the spool axis and the pe ipliery of the end headto form anehorages for clampattaehing elements to retain a yarn-clamping member against accidental detachmentfroin the spool. j

2. A yarn carrier embracing incombination a-yarn spool comprising a cylindrical bari'el, end-heads and axially disposed journals, a yarn-separating and holding` clamp having endwise distensible attaching jelements foi-.connecting the clamp to thev spool,

and anchoring members projecting from the ends of the spool intermediate the spool jour- `nais and 'the end head periplieries to engage the clamp-attaching elements and hold them against detachment against longitudinal and outward stresses.

3. A yarn carrier embracing in combination Aa yarn-spool having end heads and axially disposed journals, anchoring 4spurs arranged in offset relation to the outer faces of the end heads by which the spur-sare earried and havingl their free ends pointing inwardly to permit distensible attaching elements of a yarn-spacing and retainingclamp to be readily hooked thereto and held thereby against longitudinal and outward displacenient.

4. A tuft-yarn spooleomprising a longitudinal barrel, axial journals and metallic end heads secured toy said barrel, the end heads being formed with integral offset hooklilie members projecting inwardly aroundthe journal and adapted to afford retaining meinbers for the attachment of contractile at'- taching elements of a longitudinal yarn clamp whereby both longitudinal and outward displacement of such clamp is resisted and aceidental disengagement of the attaching elements from the spool is prevented.

5. A yarn-spool for tube fram s embracing a longitudinal barrel, axial journals and end heads, a plurality of hook-like members lo"y cated between the ournals and the peripheral portions of the spools and projecting from the end heads to forni positive aneliorages for yarn-clamp attaching elements by which said attaching elements are retained against lon' gitudinal and axial stresses and are prevent- -ineans being disposed to resist both axial and radial stresses exerted by the attaching elements,` thereby preventing disengagement of said elements from the spool through longitudinal or radial displacement of the clamp.

In witness whereof, I have subscribed the above specilication. y
